I want to set up my aquarium with a controller to auto-dose 2 part and monitor pH. I'm choosing Hydros so that I can buy the maven when it eventually comes out. I bought the BRS 2-Part Pharma Calcium & Alkalinity Starter Package for the 2-part. Here's the list of components I'm going to buy - is there anything else I should add? Do I need dosing containers? If so, which one would work with the Hydros dosing pump?
